The Alwaysfirst 4 Fixings Flat Packers are ideal for professional contractors and DIY enthusiasts who require a durable, weather-resistant solution for leveling and spacing in glazing, joinery, and flooring projects. These shims offer a reliable way to ensure structural alignment and prevent movement, though users should be mindful that they are a fixed thickness and may require stacking for precise height adjustments.

Yes, they are made from a durable material that does not rot or absorb water, allowing them to be retrieved and reused in other projects.
Yes, they are weatherproof and waterproof, making them an excellent choice for external glazing tasks.
Each packer in this specific set has a thickness of 3mm.
The material is rigid and designed to support standard glazing loads without significant compression.
Yes, the serrated surface is specifically designed to minimize movement when stacking multiple units.
Ensure the serrated side is facing the surface and consider using a slight dab of silicone or construction adhesive to hold them in position.
Since the packers are 3mm, use a combination of different sized packers or verify if a thinner/thicker shim is required for your specific tolerance.
To achieve the best results, ensure the substrate surface is clean and free of debris before placing the packers. For projects requiring height, simply stack the packers; the serrated design helps them interlock, but for high stacks, consider using a small amount of adhesive if necessary to maintain vertical alignment. Because these are plastic, they are compatible with most standard building materials, including timber, uPVC, and metal. No specialized maintenance is required; simply inspect for wear if removed after long-term installation and reuse as needed.
